    Add Limiter

    Limit the range of the 50-degree RBC VTC to a safer limit for use in K24A TSX engines.


    Adjustable cam timing is a huge performance function of the K-series engine. Unfortunately the 2004-08 TSX is not equipped with a cam phasing adjuster (or VTC) that is able to adjust with enough range to provide maximum performance, as it allows only 25 degrees of range. Hence, upgrading to an RSX-S part with greater range, in conjunction with a custom ECU tune, provides a massive power gain, especially in the lower and midrange torque curves.

    You will notice this item has the option of adding a pin to limit the cam phase range of this VTC. The reason for this is that the RSX VTC actually provides TOO MUCH adjustment range to be safe for the TSX engine. In over-rev or mis-ship situations the valves can contact the pistons at a full 50 degrees. The pin limits the range of the RSX VTC to a safe 40 degree limit for use in a 2004-08 TSX engine. It's a worthwhile safeguard!

    Customer Questions


    I'm not clear on one of the topic, but isn't OEM a genuine factory part? So is this part made from Honda/Acura factory OEM?


    Yes OEM and Geniune are used interchangeably a lot of times. This is a GENUINE part, meaning it comes straight from Acura. Read more on this topic here: What is the difference between OE, Genuine, OEM, and OER/Aftermarket Parts?

    Q:Is it good for a 06-08 k24a2 or its only for 04-5 k24a2?

    This part is ideal for all K24A2 TSX engines.

    Q:Hi , i own a 06 tsx i live in california, i was wondering if the vtc will prevent me from passing smog ? And i also have the hondata reflash do i need to be tuned on flashpro for the vtc

    No, this VTC will only work differently from stock if the computer is tuned to adjust it. With a standard tune it will not be a factor. To take advantage of this item you need a Flashpro. There may be a base map in the Flashpro for the 45 degree VTC, but you should plan on getting a custom tune.

    Q:Would this work okay with just a reflash ?
    A:The engine will work fine without a custom tune, but you will see no benefit from this part without a tune. You will need a Flashpro to take advantage of this part.
